2-Amino-4-benzoyl-1-arylpyrrole-3-carbonitriles react with arylidene malonodinitriles, β-ketoesters and βdiketones to afford pyrrolo[2,3-b]pyridine derivatives.

ABSTRACT. The versatile scaffold, N'-(2-cyanoacetyl)-2-hydroxybenzohydrazide (3) was utilized in the production of new pyridine, chromene and thiazole derivatives as antimicrobial antioxidant agents. synthetic strategy involves treatment precursor 3 with various arylidene-malononitrile 3-aryl-2-cyanoacrylate compounds to furnish substituted pyridines 5 7. interaction salicylaldehyde and/or phen...

The formula unit of the title mol-ecular complex, 2C(16)H(16)N(2)O(3)·C(16)H(16)N(2)O(2), consists of two (E)-N'-[1-(2-hy-droxy-phen-yl)ethyl-idene]-2-phen-oxy-acetohydrazide mol-ecules and one mol-ecule of 2,2'-(1,1'-azinodiethyl-idyne)diphenol, with the latter located on a crystallographic inversion center. The acetohydrazide mol-ecules are linked into a supermolecular chain along the c axis ...

The conformation of the title compound, C(12)H(17)N(3)O, is consolidated by an intra-molecular N-H⋯O hydrogen bond, generating an S(5) ring. In the crystal, inversion dimers linked by pairs of N-H⋯O inter-actions occur, resulting in R(2) (2)(8) ring motifs.

New N,N'-bis(5-arylidene-4-oxo-4,5-dihydrothiazoline-2-yl)diamine derivatives 5 were prepared in two steps from rhodanine and piperazine, or 1,4-bis(3-amino-propyl)piperazine, under microwave reaction conditions with retention of configuration. Some of these compounds were tested for in vitro antiproliferative activities and for their kinase inhibitory potencies towards six kinases (CDK5/p25, G...
